Step Up / Step Down Voltage Transformer Converters 110v to 220v /240v

We carry a wide range of 110 Volt and 220 Volt Step up and step down voltage converter transformers. Our Step 110v to 240v Up/Down transformers are reversible and can be used worldwide with 50Hz and 60 Hz. Also called power converters, most of our transformers come with Universal outlets that can accept plugs from most foreign countries. 

A voltage transformer is used to convert the electrical output of a power source to match the voltage of your device, that is, to convert 110 volt to 220/240 V OR convert 220/240 V to 110/120 Volt. A "Step Up transformer" is needed when you want to use a 220 volt foreign appliance in USA with 110v. A Step Down transformer is needed when you want to use a 110V appliance in a 220V Country. Please read our Transformer Purchase Guide before choosing a voltage converter transformer.
